Ingredient review
Ethyl Caprate
INCI: Ethyl Caprate
A lightweight, non-greasy emollient that softens skin without clogging pores.
In plain English
Ethyl caprate is a type of ester, which is a molecule made by combining an alcohol and a fatty acid. In skincare, it acts as an emollient, meaning it helps soften and smooth the skin by filling in the tiny gaps between skin cells. It feels very light and non-greasy, so it's often used in products for oily or combination skin. It also helps other ingredients spread more evenly on the skin.

Quick decision guide
Useful, but context matters
Ethyl Caprate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Ethyl Caprate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Ethyl caprate is the ester of ethyl alcohol and capric acid (a fatty acid found naturally in coconut oil and palm oil). It is a clear, colorless liquid with a very mild odor.
How it works
When applied to the skin, ethyl caprate sits on the surface and forms a thin, breathable film. This film helps reduce water loss from the skin (transepidermal water loss, or TEWL) and makes the skin feel softer and smoother. Its low viscosity also helps other ingredients like active serums spread more easily.
Pros
Lightweight feel
Unlike heavier oils, ethyl caprate absorbs quickly and leaves no sticky or greasy residue, making it ideal for daytime use and for oily skin types.
Low comedogenic risk
It has a very low likelihood of clogging pores, so it's generally safe for acne-prone skin and won't contribute to breakouts.
Cons and cautions
Sourcing concerns
Ethyl caprate is often derived from palm or coconut oil, which can be associated with deforestation and habitat loss unless sourced sustainably.
Limited standalone benefits
It works best as a supporting ingredient in a formulation and doesn't provide active benefits like antioxidants or peptides on its own.
Best for
- People with oily or combination skin who want moisture without greasiness
- Anyone looking for a lightweight emollient in serums or lightweight moisturizers
Use caution if
- Individuals with a known allergy to esters derived from coconut or palm oil
Usage tips
Safety summary
Ethyl caprate is considered very safe for topical use. It has low irritation and sensitization potential, and no significant toxicity concerns have been reported in cosmetic concentrations.
Research notes
While ethyl caprate itself has limited direct clinical studies, it is a well-known ester in cosmetic chemistry. Its safety and efficacy as an emollient are supported by decades of use and by safety assessments from bodies like the Cosmetic Ingredient Review (CIR) panel.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most other regions. Generally recognized as safe when used as directed.
- Common uses
- Moisturizers, Serums, Cleansers, Sunscreens
- Environmental note
- Derived from plant-based fatty acids, but sustainability depends on sourcing. Look for products that specify sustainably sourced palm or coconut oil.
Good to know
- Ethyl caprate is often used as a replacement for silicones in 'silicone-free' formulations.
- It is also used in some makeup removers because it helps dissolve makeup without stripping the skin.
